Is the sequence arithmetic, geometric, or neither

The first one is arithmetic, the second one is geometric, the third one is neither, the fourth one is geometric, the last one is arithmetic.

The first question goes up by a rate of -100 each time, so its arithmetic.

The second one goes up by a rate of *5 each time, so its geometric.

The third one is inconsistent so it is neither.

The fourth one goes by a factor of *-6 each time, so its geometric.

The last one goes up by a rate of -10 each time, so its arithmetic.
